The Bacolet Formation is a geologic formation in Trinidad and Tobago. It preserves radiolaria and ammonite fossils dating back to the Albian period. The formation is part of the Tobago Volcanic Group and comprises organic-rich, black pyritic siliceous mudstones and fine-grained volcaniclastic sandstones and siltstones.[1]
